I don't believe it is enough. I am sure others can tell you better than I. Flat betting, $10 dollar hands, $600 is only enough for 60 hands of play. Plus my guess is you have a win stop limit in mind, I assume your stop loss limit is the original $600? A betting spread to 1 to 10 could at a $10 dollar minimum table, be 10 units or a thousand dollars. You would have had to won quite a few hands to be able to bet $1000. Me personally, if I were up $400 over my original buy in of $600, would be looking for a loosing streak to signal my departure. Lets see what the experts say. Good luck.
